1.测定了不同发育阶段(滞育II期和滞育III期)的白背飞虱卵的耗氧量。2.胚胎发育过程中耗氧量呈实验性增加。3.滞育II和滞育III的耗氧量有所下降，滞育II在3周后达到最低水平，滞育III在2周后达到最低水平。4.胚胎发育早期可通过滞育I和滞育II逃避低氧胁迫，滞育III胚胎发育后期可通过孵化逃避低氧胁迫。5.在低氧条件下，通过降低滞育期的耗氧率，提高了一年生鱼类胚胎的存活率。
1. The oxygen consumption of Nothobranchius korthausae eggs in different developmental stages including diapause II and III, was measured. 2. Oxygen consumption increases experimentally during embryonic development. 3. In diapause II and III there is a drop in oxygen consumption, which attains a minimal level in diapause II after 3 weeks and in diapause III after 2 weeks. 4. During early development the embryos can escape from hypoxic stress by entering diapause I and II. During late embryogenesis embryos in diapause III can escape from hypoxic stress by hatching. 5. We concluded that survival of annual fish embryos is enhanced during conditions of low oxygen concentration by reduced oxygen consumption rates during diapause.
